Description
Technical field
The present invention relates to ultraviolet curing processes, and in particular to a kind of using fatty acid ester plasticiser as the PVC photocuring of solvent
Synthesis technology.
Background technique
Plasticizer is common auxiliary chemicals in a kind of plastics-production, and main function is to increase polymer plasticity and flowing
Property, make plastic products that there is flexibility.Current most popular plasticizer is phthalic ester plasticizer, but such increasing
It moulds agent and is derived from oil product, belong to non-renewable resources；It is toxic and not degradable and containing phenyl ring, in production and use process
In, seriously threaten the health and living environment of people.Currently, people develop a series of substitution phthalic acids in succession
The product of ester plasticizer, such as epoxidized vegetable oil class, citric acid ester type, polyhydric fatty acid esters class, organic phosphate class.Its
In, it is the good plasticizer of polyvinyl chloride and neoprene that epoxidized vegetable oil class is nontoxic renewable because it is derived from natural plants,
It has good stabilization to light, heat simultaneously, can absorb the hydrogen chloride that Corvic is released when decomposing, poly- to improving
Vinyl chloride product physical property and extension product service life are significant.Currently, the country is mainly with soybean oil or gutter oil
Epoxidized soybean oil or epoxy aliphatic acid methyl ester are produced for main raw material(s), the former production cost is higher, product poor compatibility；The latter
Raw material sources are unstable, and product quality is irregular.We are in a creative way using palm oil as raw material, production fatty acid ester plasticising
Agent compensates for the deficiency of the two.
Photocuring technology (UV) is to make the raw material high speed of polymerization of liquid into solid-state by the ultraviolet light of certain wavelength
A kind of smooth processing technology, photocuring reaction is substantially light-initiated polymerization, cross-linking reaction.
Summary of the invention
The purpose of the present invention is provide a kind of using fatty acid ester plasticiser as the PVC light of solvent to solve above-mentioned deficiency
Solidify synthesis technology.
The purpose of the present invention is what is be achieved through the following technical solutions:
It is a kind of using fatty acid ester plasticiser as the PVC photocuring synthesis technology of solvent, initiator 1.2gAIBME is added
Into 300ml methyl oleate, intermittent dropwise addition 0.6g pentaerythritol tetraacrylate (PETA) is dissolved in every 100ml methyl oleate
In methyl oleate, 5 average dropwise additions in totally 40 minutes, by the molten of the above initiator, methyl oleate and pentaerythritol tetraacrylate
Liquid and fatty acid ester plasticiser blend to be put into reaction kettle jointly, and 200 grams of vinyl chloride gas are being added into reaction kettle,
Isothermal reaction 3 hours at 60 DEG C of reaction temperature makes vinyl chloride and PETA that polymerization reaction occur, and in mass fraction is 5% after polymerization
Benzoin ethyl ether catalysis under through ultraviolet light can open double-bond polymerization formed heavy polymer.
Fatty acid ester plasticiser is to be made by oneself using palm oil.
It is one of aliphatic ester of 1-18 or a variety of that fatty acid ester plasticiser, which is carbon atom quantity, preferably oleic acid first
Ester, methyl hexadecanoate, methyl stearate, methyl linoleate etc..
Vinyl chloride gas reaction temperature is 40~70 DEG C.
The mass ratio of initiator and PETA are 0.5: 1~3: 1.
Dropwise addition mode is divided into continuous dropwise addition and intermittent dropwise addition, and time for adding is 20~60 minutes.
The present invention has following beneficial effect:
Photocuring technology is-item energy conservation and clean and environment-friendly technology, it is energy saving, and without solvent, to ecological environment
There is protective effect, poison gas and carbon dioxide will not be discharged to atmosphere, environmentally protective, PVC photocuring product can be used for producing middle and high end
Nontoxic PVC product, such as toy for children, disposable PVC glove, food package film, it can also be used to produce low and middle-end tradition PVC system
Product, such as PVC floor leather, agricultural film, wire cable material, photocuring PVC product not only energy conservation and environmental protection reduce operation sequence,
And efficiently, finished product quickly is prepared under ultraviolet light conditions, does not have to previously prepared PVC lotion, do not had to addition plasticizer, remove this
Except other advantages it is as follows:
1, cost of material is low, and source is wide, simple process, and products obtained therefrom purity is high has excellent performance, is widely used in plastics, rubber
The industrial circles such as glue are the favorable substitutes of petroleum product；
2, (one second to several seconds) can be completed in moment by being converted into solid paint film from liquid, and big industrial flow-line is suitble to produce；
3, all smoothness substances of resin component, non-volatile ingredient, can a hundred percent film-forming, reduce environment dirt
Dye, is typical green material；
4, solidify when low operation temperature, low energy consumption, occupied area is small.
